Two lines in Button widget and Unicode fonts

[DeusExMachina]

Hello!

Please give me step by step algorythm to create Custom button renderer (to draw two lines text in button Caption) and please tell me how to use new Unicode rendering. Included DejaVu font contains Cyrrilic symbols (I guess not). How I can use them or include them into engine? Thanks

The GWIN documentation mentions what steps need to be done for a custom render routine. You can also find a thread with sample code here.

You can find all the required information about the widget in the GHandle:

typedef struct GWindowObject {
	#if GWIN_NEED_WINDOWMANAGER
		// This MUST be the first member of the struct
		gfxQueueASyncItem	wmq;				// @< The next window (for the window manager)
	#endif
	const struct gwinVMT	*vmt;				// @< The VMT for this GWIN
	coord_t					x, y;				// @< Screen relative position
	coord_t					width, height;		// @< Dimensions of this window
	color_t					color, bgcolor;		// @< The current drawing colors
	uint16_t				flags;				// @< Window flags (the meaning is private to the GWIN class)
	#if GDISP_NEED_TEXT
		font_t				font;				// @< The current font
	#endif
} GWindowObject, * GHandle;

I'm going to prepare an example showing how to use cyrillic fonts within the following days.

I just found time to add a very small step-by-step guide to the font documentation. I hope that this helps for the meantime.

Please let me know about any upcoming problems.

Hello!

I tried step by step guide but without effect (I got last version from bitbucket). I have to modify GDISP_USE_CUSTOM_FONT define and include generated DroidSans10.c instead of userfont.h. But text renders blank...

Could you, please, send me a demo project with Cyrillic fonts?

[Joel Bodenmann]

Can you please describe what exactly you did? There happened some real life stuff and I won't be able to put together a full tutorial before wednesday.

I've added a full example using cyrillic fonts to the repository. You can find it in /demos/modules/gdisp/gdisp_fonts_cyrillic. I added some more documentation about how to use the font converter etc.
